Add mx2.mydomain.com (backup mta) in Zimbra MTA config

[mking213]

Hi,

I just set up a secondary MX server (same setup as my primary that my simbra server is currently working perfectly with) and I would like to add the mx2.mydomain.com in the servers>MTA section. Is this the correct way going about doing this and if now, how should it be done.

Regards,

Mike

What, exactly, are you trying to achieve?

Well, I just put mx2.mydomain.com... in the zimbra server MTA config I can only have one MTA. So if MX1 goes down I would like MX2 to automaticaly kick in and zimbra send emails through it instead of mx1. Make sense?

Oh forgot to mention, recieving mail when MX1 is down in a test enviroment is working fine.

I guess you're trying to set-up a backup mail server, is that it? If that's what you're doing then I'd suggest you invest in using an external DNS hosting provider that has a backup mail server. When your server goes down then the mail will be spooled by them for up-to five days then when your server is back online the mail is delivered to you. If you're trying to set-up a multi-server install then I'd suggest you read the Multi-Server Installation Guide first.

Ive got two NS/MX servers and host my own dns. let me try to explain with a diagram

MX1/NS1 MX2/NS2
- Zimbra -
Employee1 and Employee2


Employee 1 and 2 connecting to zimbra w/outlook. Zimbra sends mail through MX1.They get a reply from who they sent an email to through MX1 which relaies it to Zimbra which they pick up with outlook. Make sense?

Hope this helps..

I guess no one knows what im talking about. Here's how my mail system is now.

Sending mail: End User>Zimbra>mx1.mycompany.com>internet

Recieving Mail: internet>mx1.mycompany.com>Zimbra>End User

I've set up a secondary mail exchanger/virus/spam firewall/dns server to mimic MX1. In Zimbra Admins MTA section I cant put my secondary MX server to allow zimbra to send mail through it in case MX1 goes down. Recieving mail from MX2 works fine already.
